21. Add the last 2 numbers to get the next.
The pattern in the sequence 3, 6, 12, 21 can be identified by examining the differences between consecutive terms: 6-3=3, 12-6=6, and 21-12=9. The differences (3, 6, 9) are increasing by 3 each time. Continuing this pattern, the next difference would be 12 (9 + 3). Therefore, the next number in the sequence is 21 + 12, which equals 33.
To find the next number in the series 12, 5, 11, 21, we can look at the pattern of differences between the numbers. The differences are: -7 (12 to 5), +6 (5 to 11), and +10 (11 to 21). Continuing this pattern, we can assume the next difference will be +6 (to alternate between decreasing and increasing). Therefore, the next number would be 21 + 6 = 27.

The next composite number after 20 is 21.
The next two numbers in the sequence are... 45 & 54.
